What is the Best Reef Salt Mix?

Many people are happy to give their opinion on what makes the reef salt mix, but what is important is that you understand the building blocks of the best mix.
The first thing to keep in mind when choosing a reef salt mix will be differences between different brands. All the brands will have a label that shows what to expect from their sea salt.

If you want to end up with the perfect mix, there are a few things that you have to consider when making your decision. The common parameters to compare between brands include the amount of calcium, magnesium, and alkalinity.
The calcium compound is the most important component in the reef salt. Corals and other types of invertebrates need it for building their skeletons. The concentration recommended for good results is 400ppm. The PPM means part per million.
Magnesium is another important mineral to have in the reef water. It is often seen to be the most abundant trace mineral found in saltwater. Magnesium will work together with the calcium to help balance the alkalinity of the aquarium water. The recommended concentration is 1250 ppm.
The alkalinity is going to affect the pH level of the reef tank. With the addition of salt, you can expect that the water will become more alkaline. You have to consider the alkalinity to make sure you understand the level of bicarbonates in the water. You might have to adjust the alkalinity where possible. The alkalinity of the saltwater aquarium is recommended to be at 8 – 11 dkh.
Now, back to the question. From the details above, you want to have calcium in the range of 400 ppm, magnesium 1250 to 1400 ppm, and alkalinity kept between 8 to 11 for the salt mix.

How to Mix Reef Salt?
The first thing you will have to do is get yourself the best sea salt for your aquarium. You can easily buy this from a store near you that sells aquarium-related stuff. Most of the time, you are going to get the dry synthetic reef salt so that you can mix it with water.
Next is to gather all the necessary supplies for the work. You will need water for your mixing, and the best choice is to use deionized water for this process. You can only use tap water if the quality of the water is excellent.
